DOOR-LOCK AND ALARM DE VICE.

SPECIFICATION forming part of Letters Patent N0n 732,067, dated June 30,1903.

Application filed February 16, 1903. Serial No. 143,627. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM N. GREEK, a citizen of the United States,residing at Greeley, in the county of Greeley and State of Ne braska,have invented certain new and useful Improvements in Door-Locks andAlarm Devices, of which the following is a specification.

This invention is a lock device for doors, windows, and the like andaims to provide a simple attachment which may be carried about in thepocket and which may be readily and easily applied when desired.

Further, the invention provides an alarm means which is used inconjunction with the locking attachment and which is detachably fixedthereto, the parts being adapted for separation to facilitate theirdisposal when the device is removed andnot in use.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreifecting the result reference is to be had to the following descriptionand drawings hereto attached.

WVhile the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- Figure1 is a top plan view showing the embodiment of the invention. Fig. 2 isa perspective view looking from the rear of the device, showing theparts disposed in working position. Fig. 3 is a perspective view of thelocking attachment alone, showing the parts separated. Fig. 4 is aperspective view of the locking attachment, parts assembled so as to beadapted to be placed within the pocket.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The device consists of three essential parts-a stop 1, a lock-slide 2,and alarm means 3 for cooperation with the aforesaid The stop 1comprises a stem 4 and a lug 5, extending laterally therefrom at oneend. From the under side of the stop is projected a keeper or slot 6, inwhich the lockslide moves and which cooperates with other means to fixthe adjustment of the lock-slide relative to the stop 1. An integralscrew-pin 7 is disposed upon the under slide of the alarm means 3, whichcomprises a bell of ordinary character adapted to be set off bypressureupon a push-button 8, and said pin 7 screws into a screw-opening 9,disposed intermediate the ends of the stop 1. Anchoring means comprisingspurs 10 extend from one end of the lock-slide 2, said spurs beingadapted to enter the jamb 11 of the door-opening. The door when closedbears against the side of the lock-slide 2 opposite the spurs 10, andthus rigidly holds the lock-slide in position between the said jamb 11and the door, which is designated 12.

As before promised, the lock-slide 2 is adjustable upon the stop 1,being guided in this adjustment by a longitudinal slot 13, extendingfrom the end of the slide opposite the end carrying anchoring-spurs 10.Teeth 14, disposed upon opposite edges-of the lock-slide 2, are adaptedto fix the same at any relative adjustment, whereby the attachment maybe applied to doors or windows of different sizes. The aforesaid teeth14 upon one edge of the lock-slide are disposed intermediate the teethupon the other edge or opposite the spaces between the said teeth. Thisfeature is advantageous in that a nicety of adjustment of the lock-slideto different-sized doors and windows is secured. The slot 13, as beforementioned, serves to guide the lock-slide in its movement upon the stop1, a clampscrew 15 cooperating with the slot 13 to direct this movement.The teeth 14 interlock with the upper and lower sides 16 of the keeper6, thereby locking the lock-slide at any desired adjustment upon thestop 1.

In the operation of the device, the parts being disposed in thepositions most clearlyindicated in Fig. 1, any movement of the door toopen same will depress the push-button 8 of the alarm means, andimmediately the same will notify the occupants of the dwelling of suchmovement of the door. This movement, however, is limited by the lug 5 ofthe stop 1 in a manner which will be readily seen, so that though thealarm may be set off, yet at the same time the door is maintainedpractically locked.

It is contemplated when the device is not in use to remove the alarm orbell 3 from the stop 1 and to adjust the stop 1 and the lookslide 2 withreference to each other so as to occupy the smallest possible amount ofspace. This is desirable, since it is purposed to place the lockingattachment within the pocket when not in use, and when the parts of theattachment are to be so disposed thelock-slide is removed from thekeeper 6 and the same replaced, so that the spurs 10 will be disposed tolie against the lug-5. (See Fig. 4.) The clamp-screw is used in the samerelation as heretofore described and prevents the accidental separationof the lug 5 and the stop 1. An opening 17 is located at the end of thestop opposite the lug 5, and the looking attachment may be placed upon akey-ring or the like when it is disposed within the pocket.

I am not to be restricted to the exact structure of parts as illustratedin the drawings; but such changes as are included within the broadspirit of the invention and the scope of the appended claims may bemade.

Having thus described theinvention, what is claimed as new is- 1. In adevice of the character described, in combination, a locking attachmentcomprising a stop, a loop projected from the said stop, a lock-slide forrelative adjustment upon the stop, and positive interlocking meansbetween the lock-slide and the loop for fixing the adjustment of thesaid slide upon the stop, substantially as described.

2. In a device of the character described, and in combination, a stop, akeeper or loop projected from the said stop, a lock-slide adapted forrelative adjustment upon the stop and provided upon opposite edges withteeth, said teeth being adapted to interlock with the keeper to fix theadjustment of the lock-slide upon the stop, substantially as described.

3. In a device of the character set forth, and in combination with astop, a keeper or loop projected from the under side of the said stop, alock-slide adapted for relative adj ustment upon the said stop andprovided upon opposite edges with teeth, said teeth being adapted tointerlock with the loop upon the stop to fix the adjustment of thelock-slide thereon, and guide means adapted to cooperate with the keeperto direct the lock-slide in its movement upon the stop, and alarm meanscarried by thestop, substantially as described.

4:. In a locking device and alarm for doors and the like, incombination, a stop having a lug laterally projected from one end and akeeper or loop projected from the under side thereof, a lock-slideadapted for relative adjustment upon the aforesaid stop, teeth disposedupon opposite edges of the lock-slide and adapted to cooperate with thekeeper or loop upon the stop and to fix the adjustment of the lock-slideupon the stop, spurs disposed upon one end of the lock-slide, a 1011-gitudinal slot extended from the opposite end of the said slide, anda-clamp-screw adapted to cooperate with the said slot to preventdisplacement of the lock-slide from the stop, and alarm means secured tothe stop and adapted to be set off by opening movement of the door,substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM N. GREER.
